Syncfusion's 2025 Volume 4 release introduces a JavaScript PDF Library that enables fully client-side PDF operations without backend dependencies. The library supports creating, editing, signing, extracting, and redacting PDFs directly in the browser using JavaScript or TypeScript. Key features include multi-page document creation with custom layouts, text rendering with Unicode and RTL support, annotations, interactive forms (AcroForms), digital signatures using X.509 certificates, bookmarks, hyperlinks, and content extraction. It works across JavaScript, TypeScript, Angular, React, Vue, ASP.NET Core, and ASP.NET MVC platforms, offering a secure alternative to server-side PDF processing for applications in finance, healthcare, and compliance.
